Confirmed hospitalizations due to influenza is an indicator of the overall burden of influenza in the United States and predictions of confirmed hospitalizations can help public health planning and interventions.

What will the total number of confirmed hospitalizations due to influenza be in California for the weeks shown below (starting on Sunday and ending on Saturday)?

Each of the subquestions will resolve based on the weekly total number of confirmed influenza hospitalizations for California between the respective start date and end date as reported in this data set provided by the CDC.

Information on daily hospitalizations can be found in this data set (the COVID-19 Reported Patient Impact and Hospital Capacity by State Timeseries) in the field name previous_day_admission_influenza_confirmed. Note that the field previous_day_admission_influenza_confirmed counts the number of hospitalizations due to influenza on the day previous to when it is reported. When resolved, we will adjust this field to count the number of hospitalizations from the start date to the end date.

Additional information on this data and further explanations can be found in Field #34 of the COVID-19 Guidance for Hospital Reporting and FAQs For Hospitals, Hospital Laboratory, and Acute Care Facility Data Reporting).

Each of the subquestions will be resolved based on data 2 weeks after the respective end date.

Here is a plot with past hospitalizations in California:
